Apogee Instruments MQ-650/AM-320 Bundle - Underwater/Reef Tank ePAR Quantum Meter Bundled with AM-320 Submersible Sensor Wand - Includes Apogee Instruments Neoprene Case

DR BRUCE BUGBEE: Apogee PAR meters have been designed and refined by Dr. Bruce Bugbee, a world-famous crop physiologist.
UNDERWATER ACCURACY: The MQ-510 ensures precise PAR measurements underwater by applying an immersion effect correction factor. It measures photons between 400 and 700 nm, providing a single PAR reading in µmol m-2 s-1 with less than 5% uncertainty. Its stable calibration boasts an accuracy drift rate of under 2% per year, unlike hobby-grade meters.
NEW ePAR RANGE: Lab-grade measurement reveals photosynthetic activity from 400-750 nm, expanding beyond the traditional 400-700 nm PAR range. Dr. Shuyang Zhen and Dr. Bruce Bugbee spearheaded the defining research. The MQ-610 accurately measures far-red photons (700-750 nm), vital for next-gen LED fixtures, sunlight, and other sources not captured by standard PAR meters.
FEATURES: The rugged detector measures photosynthetic photons from 400-700 nm from any light source by taking instantaneous or logged measurements; immersion correction-factor calibrated in for accurate UNDERWATER par-measuring. Bundle includes AM-330 submersible, telescoping sensor-wand.
RUGGED DESIGN: The sensor head is made of machined aluminum and fully potted, making it waterproof and rugged. The tangle-free cable facilitates measurements over a large plant canopy, while still allowing the user to view the high-contract display screen. NOTE: Handheld-meter display is NOT waterproof

Apogee Instruments MQ-650: Underwater ePAR Quantum Meter Bundled with AM-320 Water Submersible Sensor Wand Includes Apogee Instruments Neoprene Case

FOR SCIENTISTS & SERIOUS GROWERS – Designed by world-renowned crop physiologist, Bruce Bugbee, PhD, the MQ-650 ePAR (extended-range PAR) underwater quantum meter is the premium tool of choice among leading scientists and serious growers for accurately measuring the photosynthetically active radiation (PAR) underwater. Package includes an AM-320 three-piece 3′ corrosion-resistant wand and an Apogee neoprene carrying case.

MEASURING PAR IS CRITICAL – An accurate PAR meter is critical for measuring the intensity of light used in the precision growing of plants and other photosynthetic organisms in greenhouses, growth chambers, farms, gardens, aquariums, and additional agricultural systems. Our underwater quantum meters are specifically designed to measure the intensity of light underwater for biological, chemical, and physical processes in natural waters and aquariums.

UNDERWATER ACCURACY – Underwater PAR measurements can read low when a quantum sensor is calibrated for air. The MQ-510 applies an immersion effect correction factor to get instant, accurate measurements underwater. Precisely measures and combines the intensity of all photons between 400 and 700 nm to give a single PAR reading in µmol m-2 s-1 within 5% uncertainty. Unlike hobby-grade PAR meters, our meter has a stable, accurate calibration with an accuracy drift rate of less than 2% per year.

QUALITY ePAR METER – Unlike cheaper LUX or footcandle sensors which are sometimes marketed as grow light meters, but are meant for measuring light for human vision, our meters feature a laboratory-grade ePPFD (extended photosynthetic photon flux density) optical detector precisely calibrated to measure the light intensity in µmol m-2 s-1 of the specific color wavelengths (including far-red) emitted by LEDs, HPS, MH, sunlight, and other light sources utilized by plants/corals etc. for photosynthesis.

NEW ePAR RANGE – Laboratory-grade measurement of the newly defined 400-750 nm ePAR has been found to be photosynthetically active beyond the traditional 400-700 nm (PAR). Much of the transformative work to define the ePAR range was conducted by Dr. Shuyang Zhen and Dr. Bruce Bugbee. The MQ-610 can accurately measure far-red photons (700-750 nm), found in many next-generation LED fixtures, the sun, and other light sources, which cannot be measured by traditional PAR meters.

EXTREMELY ACCURATE & STABLE – Precisely measures and combines the intensity of all photons between 400 and 750 nm to give a single ePAR reading in µmol m-2 s-1 within 5% uncertainty. Our ePAR meter has a stable, accurate calibration with an accuracy drift rate of less than 2% per year.

RUGGED & EASY TO USE – Quantum sensor head is machined aluminum and potted solid with epoxy for years of use in harsh environments, including underwater. The handheld meter is attached by a cable and displays real-time readings, records samples, and logs average intensity and daily light integral (DLI) measurements. Unlike the sensor head, the handheld meter is not waterproof.
